I adore a good twice baked potato — I do not adore refilling potato skins like a surgeon and hoping they don’t rip. Enter the Twice Baked Potato Casserole: all the creamy, cheesy, bacon-filled bliss without the fussy scooping or fragile potato boats.
It’s cozy, easy, wildly crowd-pleasing, and pairs with everything from steak to roasted chicken to your holiday turkey. If you need a side dish that makes everyone happy, this is it.
And here’s exactly why it works:
- No scooping, no stress. All the twice-baked flavor with a fraction of the work.
- Loaded and comforting. Bacon, cheddar, sour cream — the full steakhouse experience.
- Creamy center, golden top. The perfect texture every single time.
- Feeds a crowd. A generous, holiday-ready casserole that reheats beautifully.
- Flexible and customizable. Swap cheeses, add herbs, or toss in extra bacon — it all works.
What You'll Need & Why
- Russet Potatoes: The best potato for baking and mashing — fluffy, sturdy, and made for soaking up all that creamy, cheesy goodness.
- Butter, Sour Cream & Heavy Cream: The richness trifecta. This combo gives the casserole its silky texture, subtle tang, and over-the-top comfort.
- Cheddar + Monterey Jack: Sharp flavor from the cheddar and melty, stretchy, ooey-gooey magic from the Monterey Jack. A twice-baked potato should be unapologetically cheesy.
- Green Onions & Garlic: Roasted right alongside the potatoes for a deeper, sweeter flavor. Don’t skip this step — it’s small effort, big payoff.
- Bacon: Because bacon makes everything better. Fold some into the casserole and save a generous handful for the top. Zero regrets.
Swaps & Flavor-Boosting Variations
Give this cozy classic your own spin—once the creamy potato base is there, the mix-ins and toppings are completely up to you.
- Love potato skins? Add ’em in. I leave them out because I’m a smooth-and-creamy girlie, but if you love that rustic bite, chop the skins and fold them right into the casserole before baking.
- Swap the sour cream. Greek yogurt works beautifully and adds the same creamy tang. Full-fat is best for flavor and texture.
- Choose your cheese adventure.
Any good melting cheese works — Gruyère, fontina, smoked gouda, pepper jack, or even a sharp white cheddar. Just shred it yourself. Bagged cheese won’t melt the same and will ruin that velvety texture. - Make it Southwestern. Stir in a can of mild green chiles or sautéed poblanos for a Tex-Mex twist. We call this version “Papas,” and it is outrageously good.
- Boost the protein. Fold in cooked chopped ham, pulled chicken, or crumbled breakfast sausage for a heartier casserole that can double as a main dish.
- Add fresh herbs. Chopped chives, parsley, or thyme bring brightness to all that richness. Rosemary works in small amounts, too.
- Dial up the heat. Add cayenne, smoked paprika, or diced jalapeños if you want a little kick.

Tips & Tricks
A few simple tricks will keep this casserole ultra-creamy, perfectly seasoned, and guaranteed to disappear fast.
- Shred. Your. Own. Cheese. This is an ooey-gooey casserole, which means meltiness matters. Pre-shredded cheese is coated in anti-caking powder that keeps it from melting smoothly — it turns gloopy and grainy. Grab a block and shred it yourself. Your future self will thank you.
- Cook the bacon until it’s actually crispy. Soft bacon disappears into the potatoes. Crispy bacon adds texture, crunch, and little salty pops of flavor in every bite. It’s worth the extra minute.
- Make it a main dish. Fold in shredded rotisserie chicken, diced ham, or even browned breakfast sausage before baking. It becomes a full, cozy meal that feeds a small army.
- Turn leftovers into the BEST potato soup. Add a few scoops of the casserole plus chicken broth to a saucepan over medium-high heat. Stir until creamy.
- Want it thinner? Add more broth.
- Want it thicker? Add less broth.
- It tastes like a loaded baked potato soup you “accidentally” made on purpose
Make Ahead Instructions
If you like getting ahead of the game, this casserole is a perfect make-ahead situation.
- You can prep this twice baked potato casserole up to 2 days before serving.
- Add freshly crisped bacon on top right before serving for the best texture.
- Assemble the casserole completely, but don’t bake it.
- Cover tightly with foil and refrigerate.
- When ready to bake, let it sit at room temperature for 30 minutes so it heats evenly.
- Check the top — if it looks a little dry from chilling, drizzle 1–2 tablespoons of heavy cream or broth over the surface.
- Bake at 350°F, covered, for 15 minutes.
- Remove the foil and bake for an additional 20–30 minutes, until hot and bubbly with a lightly golden top.
Slow Cooker Method
Finishing this loaded twice baked potato casserole in the slow cooker is a total holiday lifesaver. It keeps the potatoes hot, frees up oven space, and you can serve straight from the crock — one less dish to wash!
Here’s how to do it:
- Prepare the casserole mixture exactly as instructed in the recipe card.
- Transfer everything into the bowl of a greased slow cooker instead of a baking dish.
- Heat on LOW for 2–3 hours or HIGH for 1–1½ hours, until hot and bubbly.
- Give it a gentle stir halfway through if your crock runs hot on the edges.
- Switch to Keep Warm and serve right from the slow cooker — it’ll stay perfectly creamy and cozy for hours.
Bonus: This is the best option for potlucks, parties, and big holidays when oven space is precious real estate.

Twice Baked Potato Casserole Recipe
Ingredients
- 8 medium russet potatoes approximately 5-6 pounds of potatoes
- 1 head garlic
- 1 bunch green onions
- avocado oil
- 1 lb bacon
- 2-3 tablespoon all-purpose seasoning
- 1 cup butter, melted
- 1 cup sour cream
- 1 cup heavy cream
- 1 cup cheddar cheese, grated
- 1 cup Monterrey Jack cheese, grated
- kosher salt and fresh ground pepper, to taste
Instructions
The Potatoes, Garlic, and Green Onions
- Bake the potatoes in a 400° oven for about an hour or until they're tender.
- Trim the top ¼ inch off the top of a garlic bulb. Place the garlic cut-side up onto a piece of foil along with the white part of the green onion, drizzle with avocado oil, and sprinkle with kosher salt. Wrap the garlic and onion in the foil.
- Place the packet into a small baking dish and add that to the oven along with the potatoes. The garlic and onions will be done anywhere from 45 minutes - 1 hour. If the potatoes need more time in the oven, simply remove the garlic and onions and let them cool while the potatoes finish cooking.
The Bacon
- Cook the bacon on a parchment lined baking sheet along with the potatoes, garlic, and green onions until crispy.
- Once cooled, finely chop it. Reserve some for topping the casserole later on.
The Casserole
- Cut the slightly cooled potatoes in half and scoop out the insides into a large mixing bowl. Mash or breakup the potato pieces to your liking. You can make the pieces as large or as small as you would like.
- In a separate mixing bowl, combine the all-purpose seasoning, melted butter, heavy cream, sour cream, half of the grated cheeses, and the ¾ of the bacon. Mash the roasted garlic cloves and mince up the roasted green onion tops and also add those to the mixing bowl. Mix everything to combine.
- Pour the butter mixture over the potato pieces, mixing to throughly combine. Add the casserole mixture to a lightly greased 9x13 baking dish. Top with remaining cheese and bake in a preheated 400° oven for 20-25 minutes.
- Garnish with the sliced tops of the green onions. Enjoy!

Storage & Reheating
- Fridge: Store leftovers in an airtight container for up to 3 days. The flavors actually get even better as everything settles.
- Reheat (Quick): Microwave in short increments, stirring between bursts so it heats evenly and stays creamy.
- Reheat (Best Texture): Warm in a 300°F oven, covered, for 20–30 minutes, until hot and bubbly. Remove the foil for the last few minutes if you want to re-crisp the top.
- Freeze: Freeze leftovers (or the whole casserole unbaked) in an airtight container for up to 3 months. Thaw overnight in the fridge before reheating for the smoothest, creamiest texture.
- Pro Tip: If the casserole looks a little dry after reheating, stir in a splash of heavy cream or broth — it brings the creamy magic right back.
You Asked, I Answered
Do I need to use russet potatoes for this recipe?
Yes — russets are the best. Their high starch and fluffy texture make the casserole creamy without turning gummy. Waxy potatoes (Yukon Gold or red) can make it dense or gluey.
Is this recipe gluten-free?
Yep! Everything is naturally gluten-free. Just check your bacon and add-ins to be sure they’re labeled GF.
Can I leave the skins on?
Absolutely. I prefer a smooth, creamy texture so I peel them, but mashing the skins in adds heartiness and works great if you like it rustic.
Why did my potatoes turn gummy?
Two main culprits:
1. Over-mixing. Potatoes can get overworked and gluey if you stir too aggressively. Fold gently.
2. Using the wrong potato. Yukon Golds and red potatoes can get dense or pasty when mashed. Russets always deliver the fluffiest texture.
Can I prep this casserole the day before?
Yes. Assemble it up to 2 days ahead, cover, and refrigerate. Add a splash of cream before baking if it looks dry.
Can I use different cheeses?
Definitely. Use any good melting cheese like Gruyère, fontina, or smoked gouda — just shred it yourself for the creamiest melt.
Can I freeze this casserole?
Yes. Freeze leftovers or the unbaked casserole for up to 3 months. Thaw overnight in the fridge, then bake until hot and bubbly, adding a splash of cream if needed.
Can this be a full meal instead of a side?
A thousand times yes. Stir in rotisserie chicken, diced ham, or cooked sausage before baking and it becomes a cozy, filling main dish.
